HF Polyester welder supplier.The following standards are used to determine the quality of the PP packaging belt production line of the embossing machine

　　1. The packaging machine belt should have good toughness. If the embossing machine PP packaging machine belt is repeatedly folded, it is easy to break if the toughness is not good. Pattern issues, the pattern must be aesthetically pleasing, and there should be no pressure deviation.

　　2. The quality of the embossing machine PP packaging machine belt is generally better when it is white (other colors should be bright), as these are not easily mixed with old materials.

　　3. The packaging machine belt should have a glossiness, and this type of packaging machine belt is generally produced from all materials. Stable tension. If the packaging machine comes with powder additives, the glossiness will be greatly reduced.

　　4. The width error of the packaging machine belt is generally plus or minus 0.3mm. In the production of such a packaging machine belt, the material is evenly cut and the quality is relatively uniform, so there will be no good or bad situations.

　　5. Some packaging machines have brand new materials on the outside and filling materials in the middle (extremely poor). As long as you cut and look at the cross-section, you can see that the black core inside is of poor quality.

　　The color issue of the packaging machine belt is difficult to say due to the different grades of the packaging machine belt. The transparent packaging machine belt is currently the best packaging machine belt. The quality of the packaging machine belt completely depends on the purity of polypropylene, and the higher the purity of polypropylene, the better the tension of the packaging machine belt.

　　Melting of plastic particles - Pressing - Forming - Cooling - Wrapping - Packaging - Warehousing. The PP packaging belt production line of the embossing machine adopts a mesh structure packaging material produced by heating, melting, stretching, and cooling polypropylene. The basic parameters that affect the quality of the packaging belt production line are tension, length, curvature, elongation, etc. When the tension and other parameters are the same, the longer the length, the lower the cost. The PP packaging belt production line of the embossing machine introduces four of the world's most advanced packaging belt production lines, using processing technology to produce high-strength, high-quality, and environmentally friendly 3000 meter new material packaging belt production line. The unit price cost per meter is much lower than the unit price of domestic recycling belts and similar imported belts.
